Yoshio Kôsaku was a Rangaku expert and one of the chief official Dutch translators stationed in Nagasaki. This position was passed down within the Yoshio family, and their house, which came to contain a great many Dutch/Western artifacts over the years, was sometimes known as Kômô yashiki ("the Dutch mansion," or "Mansion of Red-Hairs").
